As a business owner who's been trying to get her own company t-shirts done for well over two years now, I can understand the hold up. I'm sure this isn't universally true, but I've come to realize that the t-shirt screen printers I've approached are flakes.
So far, the best I've been able to do was company underwear. LMAO
Anyway, I'd be down for a FABO shirt or two if this ever happens. Small will be fine, or medium if they're 100% cotton.
